Timeline for Near Real-time Ambient Air Quality Data Flows

Flows for continuous and automated gas chromatograph (AutoGC) data, depicting and describing the time it takes for near real-time ambient air quality data to be collected, retrieved, processed, and posted to the website.

Near Real-time Data Flow for Continuous Gaseous and Particulate Data

The figure above shows the total timeline of 60 minutes for TCEQ and partners to monitor continuous, near real-time ambient air quality and upload the data to our webpages. The timeline for each step is as follows:

Sample collection - 15 minutes

Our system calls site to pick up data - every 20 minutes

Data processing - 10 minutes

Data posted to TCEQ website - 15 minutes

Near Real-time Data Flow for AutoGC Data

TCEQ and our partners measure ambient air quality for volatile organic compounds using AutoGCs. The figure above shows the total timeline of 150-178 minutes to collect, analyze, and upload that data to our webpages. The timeline for each step is as follows:
